14 Claims. (Cl. 268-126) This invention relates to window regulators andmore particularly toa window regulator adapted for straight linemovement between denite limits.

It is an object of the present invention to provide a window regulatorparticularly adapted for the rear pane in an automobile, but which canbe readily applied to raise and lower any window or similar appliancedesired.

It is a further object of the present invention to provide such a Windowregulator in which the point of attachment to the window has straightline movement whereby all sliding connections between the window and theregulator are avoided.

Another object of the present invention is to provide a window regulatorutilizing the planetary gearing arrangement for obtaining straight linemotion of the connecting point.

A further object of the invention is to provide a novel connecting meansbetween the window retaining channel and the regulator; and otherobjects will becomeapparent from the course of the followingdescription.

A structure embodying the invention is illustrated in the accompanyingdrawings and will be hereinafter fully described, the invention residingin certain novel features which will be particularly pointedv out in theappended claims.

In the drawings: 1

Figure 6 is a further detail of the spring clip arrangement on the line6-6 of Figure 5, and looking in the direction of the arrows; and

Figure 7 is a detail section view similar to Figure 5 illustrating themanner of connectingand detaching the window from the regulatormechanism.

Referring to the accompanying drawings in which like numerals indicatelike parts throughout the several views, the car has a rear door 10mounted on a rear panel 12, the rear panel containing a window pane L14adapted to raise and lower between definite limits.` Y y `A seat 18 isVlocated adjacent and beneath the window 14 and is provided with an armrest 20 fitting on the wall adjacent the window.` The side of themachine between the arm rest 20 'and the seat 18 is padded as shown at21, the padding being cut away to accommodate an operating handle 24 ofa window regulator, generally designated 2,6, the window regulator 26forming the 65 subject matter of the present invention. 1'

As best seen in Figs. 2 and 3, the window regulator 26 is mountedbetween an inner wall 27 and an outer wall 28 of the machine, with thevhandle'24 projecting through the inner Wall 70 thereof and into theinterior of the machine.V

The regulator 26 is mounted on a plate '30 compri'sing an annular flange31 and a disc-like body member 32 having an aperture 33 therethrough.

A clutch housing l35 is mounted in the aperture 75. 33, the clutch cuphaving a disc 36 at the inner end thereof forming a bearing surfaceforan arm 37 to'be later described. The clutch housing encloses Ythedrive n mechanism for transmitting motion between the handle 24 Vandthe"80 various gears going to make up the regulator.

The clutch comprises a spring 40 which fits tightly within the housing35 and has inturned ends 42 and 43 which engage with either a driver 46,46Y or with a driven member 48. 'I'he ar-.S rangement of the spring issuch that if force be transmitted to it in either direction from .thedriven member 48, the spring tends to tighten within the housing 35 andprevent movement of' both the driven member 48 and the driving member 46and forces applied to the spring through the driving member 46 in eitherdirection tend to loosen the spring member from the inner wall of thehousing 35 and permit movement to be transmitted between the drivingmember 46 andthe driven member 48. Further details of this mechanism aregiven in the patent to Charles L. Coughlin, United States Patent No.1,686,682, issued October 9, 1928.

The driven member 48 is provided with av circular disc 50 on the outerend thereof to fit in the housing 35 to preventk the movementv of thevspring past the end of the driven member 46, 46 and to form a guide forthe driven member within the clutch housing.

A second disc 52 is formed integrally with the disc 50, but is madeslightly smaller to forma shoulder between the discs 50 and 52. A gear54 is mounted about the disc 52 and is fxedly at-V tached to the plate32 and held against rotation V110 by rivets 56 or equivalent fasteningmeans which integrally joins both the flange 36 and the gear 54 with themounting member 36.

A gear 57 is xed to the outer face of the disc 5 52 by means of rivets53, motion being transmitted from the driving member 48 to the gear 57through a plurality ofY pins 59 formed iiitegrally on the outer face ofthe disc 52. 'I he rotary arm 37 is mounted on the outer periphery ofthe flange 36 of the housing 35 for ,I The arm 37 may have a pairrotation thereon. of outstanding flanges 66 turned inward towards v theinner wall 27 of the automobile to lend strength to the arm and permitthe ruse of lighter materialin its construction. The Varm 37 car- Thelarger of the two gears 63 is in constant mesh with the gear 57 ofthedriving member and isv turned thereby. The gear 65 and the gear '54 areboth in constant mesh with an idler 76 which as Y, shown'in Fig. 3, isrotatably mounted on the army r37 and transmits rotation from the gear63 through the gear 65 and the idler70 to rotate the arm 37 aboutitsilange bearing 36.

The gear 57 is formed with a shroud66 which cooperates with'a pluralityof globular buttonsk 67 formed integrally on the outer lace of the rgear54 to retain the gear 63 against wabbling.

The gear .63 has an outstruck portion 74 thereon which mounts an arm 76carrying a connecting pin, generally designated 77. The details of thepin 77 and the mounting arm 76 are best shown in Figures 5, :6, and 7.

Referring to those figures it will be seen .that the arm 76 is providedwith a connecting which hasY been generally designated 77 and 46 'whichfits through an aperture 7S in a mounting bracket 8(7), the bracket 86being spotwelded orv otherwise suitably fixed to the channel 81 whichretains the window pane 14 in theV usual `manner. The hole 78 may beelongated'hori- 454 zntally to allow for slight variations the nt.-

ting of the glass in its guideways and to allow also for variations fromthe correct position of the regulator.

The connecting pin 77 comprises a shank 84 ohaving an enlarged portion85 thereon and a button 87 formed on the side ofthe enlarged portionopposite the shankl S4, the enlarged pore tion 85 forming shouldersbetween the shank 84,

,n `vthe enlargement 85, and the button 87. The end F15-fof the shank 84projecting through the arm 76 may be riveted tothe arm as shown or maybe otherwise suitably fastened thereto. Y A spring 90 having avertically elongated aper ture 91 therein, fits over the button 87 toretain. 6o the bracket 80 connected therewith. The lower edge of thevertical flange of the bracket 80 is bent inwardly towards the regulatoras shown. at 93 and is engageable with an outturned portion` P 94 on thespring to dislodge the spring from its lnormal position duringassembling, whereby assembly may be eected with the button 87 belowA theplane of the window sill, the method of accomplishing this Vbeingclearly illustrated in Fig. 7.',

It will be noted that the system includes two 770-.Vv levers. One leverwhich may be considered the' plateu37 is mounted for radial movementabout the axis of the handle 24 and has a length equal to the distancebetween the center of rotation of.

the handle 2,4 andthe center of the "gear 63.

75" The second lever comprising the gear 63 and the arm 76 is pivotedabout the point 66 and has a length equal to the distance between thepivot 68 and the pin 77. The length of the levers is equal, and theratio of the gears 57, 63 and 54, and 65 is suchthat the average angularspeed of the second lever about its axis is twice the angular velocityof the first lever about its axis. Hence, `with this arrangement, thepoint 77 must oiv'necessity move in a vertical straight line between itslowest and its highest point.

To assemble the device, the window regulator *is moved to its uppermostposition and the window pulled inwardly out of its casing. lThe spring90 may then be dislodged by pressure oi the bent in portion 93 of thebracket 36 against the bent out portion 94 lof the spring 96 and thebracket inserted over vthe button, to engage the port 78 ,thereoven rThespring 90 then takes eiect to press the bracket rmly onto the button andretain it4 in this position. The window is then replaced in the casingand thefremoved parts of the casing replaced to form av permanent con-`nection.

It will be noted from Fig. 5 that the horizontal attaching ilange of thebracket 86 is cut away to provide the vertical flange Vof the bracketwith an extended tongue 95, at the end of which the clip attachment islocated. This accommodates the spring 90 during raising and lowering ofvthe window. n 'l Operation In operation, when the button 77 has beeninserted through the bracket 80 the window is raised or lowered byrotation of the handle 24 in the appropriate direction. Rotation of thehandle 24 transmits motion through the drive member 46, 46^to the drivenmember 48 and thence to the 1 gear 57. Rotation of the gear 57 causes-acor-l responding: rotation of the gears 63 and 65 which are.y fastenedtogether. Rotation of the gear 65 rotates the idler 70 which is in meshwith the stationary gear 54 andpro-duces rotation of the` arm 37.

It will be noted particularly that by properly arranging the sizes ofthe gears that as the gear 63 swings around the center line of thehandle,v
